About

There is no scientific controversy about the safety or effectiveness of vaccines. This Cause is dedicating to supporting awareness of the value of vaccines in the face of a small minority who deny the overwhelming scientific and medical evidence.

"Immunisation is a proven tool for controlling and eliminating life-threatening infectious diseases and is estimated to avert between 2 and 3 million deaths each year. It is one of the most cost-effective health investments, with proven strategies that make it accessible to even the most hard-to-reach and vulnerable populations. It has clearly defined target groups; it can be delivered effectively through outreach activities; and vaccination does not require any major lifestyle change."
